The best plan is to reduce Black's attacking potential. The queen is helpful for defending the king along the third rank.
12... e5f4  13. g4f4  13... c6e5 with firm control of the e5-square and a potential attack on the queenside, Black is clearly better. 14. e3d4  14... c8h8 As is usually the case, after both sides have castled the position on the board no longer looks strange to the standards we're used to. Black has a clear plan of attack on the queenside, while it's not clear what White should do.
